How to create a multi-valued and drop-down custom attribute on OIM

Question

Hi experts, 
 I need to create a drop-down multi-choice custom attribute with a limited list of values that once all values has been selected, they has to be storage on a multi-valued custom attribute on "Person" database table. I created a custom multi-valued attribute through a Person table extension but when I tried to edit the permissions for the Person database table on the Designer and I check "multi-valued column" option on the "Properties/More" tab, it automatically disable the "Define list of values" properties on "Properties/Column" tab. 
 
 Am I doing the correct process to create this type of attributes or there are other steps to do it properly? 
 Thanks in advance!

I still think this should be possible using a custom property editor. To be more specific, copy VI_Common_PropertyEditor and write your own implementation of it (maybe use the HoverPanel for the design). Then assign your new component as "component to edit a value" in your property definition (for the Person editor form it's in the VI_Employee_Edit configuration section). 
 Not saying it will be quick or easy, but it should work like that.

The HoverPanel display node is pretty flexible for these kind of things. The Head part is displayed and when you click on it (configurable) the Content part pops up.
